Guru was good at describing things with his words but sometimes it seemed like he was too monotone. not that other rappers really changed emotion a lot either, but at least like a little bit. your voice really is like 1/4th of your rapping ability imo and its the one thing you cant really change.
just ask AZ why he was never as big as Nas or Scientifik why he was never big period or Meek Mill why he can say the same phrases over and over again but it still sounds catchy.
its the voice, which is another reason why I feel Tupac and Biggie arent even close tbh. I cant even understand half of what Tupac is saying sometimes, I never thought that when Biggie rapped.
Sadat X says some funny shit, no way would I want to listen to one of his cds start to finish
Lil Wayne sounds like a teenager and thusly is not taken seriously by most people except those who hate him
Currensy is a better rapper than Lil Wayne but sounds like he has marbles in his mouth
Kool G Rap is one of the few who was able to turn a less than desirable voice into success but his was more of a lisp than anything so when you rap fluidly enough its not as noticeable
MF Doom always sounds like he's rapping in the opposite direction and just randomly..... trails off lower and lower in volume sometimes...
